The following description is presented to enable one of ordinary skill in the art to better understand the embodiments of the present application.

1. Double connection (Dual Connectivity DC)

Dual Connectivity refers to the network providing resources of two network nodes/base stations (access network elements) for the UE, one of which is called Master Node (MN) and the other is called Secondary Node (SN). Each network node may use one cell to serve the UE; carrier aggregation (Carrier Aggregation, CA) techniques, i.e. configuring the UE with multiple serving cells controlled by the node, may also be used. One or more cells controlled by one node constitute a Cell Group (CG). The master node MN controls the master cell group (Master Cell Group, MCG) and the secondary node SN controls the secondary cell group (Secondary Cell Group, SCG). Each Cell group contains a Special Cell (SpCell) and a series of Secondary cells (scells). The special Cell is called a Primary Cell (PCell) in the MCG, and the special Cell is called a Primary secondary Cell (Primary Secondary Cell, PSCell) in the SCG. SpCell uses the primary carrier in one cell group, while other secondary cells use the secondary carrier, and resource scheduling within one cell group is performed by SpCell.

In NR, if the UE applies the SCG configuration provided by NW and including the synchronization reconfiguration indication (ReconfigurationWithSync IE), and the UE successfully completes RACH at the candidate/target PSCell, then a PSCell change is successfully made for the UE.

CG-Config: this message is used to transmit SCG radio frequency configuration generated by the SgNB or SeNB. It may also be used by the CU to request the DU to perform certain operations, e.g. to request the DU to perform a new lower layer configuration.

CG-configmnfo: this message is used by the master eNB or the gNB to request the SgNB or the SeNB to perform certain operations, such as setting up, modifying or releasing SCGs. The message may include additional information, for example to help the SgNB or SeNB set the SCG configuration. The CU may also use it to request the DU to perform certain operations, such as setting up or modifying an MCG or SCG.

2. Conditional primary and secondary cell group additions or changes (Conditional PSCell Addition or Change, CPAC);

1) Conditional primary secondary cell addition (Conditional PSCell Addition, CPA);

the conditional primary and secondary cell addition is a primary and secondary cell addition that the UE evaluates the execution condition and performs after the execution condition is satisfied.

The CPA configuration comprises configuration and execution conditions of the CPA candidate cell, and the execution conditions may comprise one to two trigger conditions.

2) Conditional primary secondary cell change (Conditional PSCell Change, CPC);

The conditional primary and secondary cell change is a primary and secondary cell change that the UE evaluates the execution condition and performs after the execution condition is satisfied. And after receiving the CPC configuration, the UE starts to evaluate the execution conditions, and after the primary and secondary cells are changed and triggered, the UE stops evaluating the execution conditions.

The CPC configuration comprises the configuration of the CPC candidate cell and execution conditions, which may comprise one to two trigger conditions. Upon successful completion of the primary and secondary cell change procedure, the UE releases all stored CPC configurations.

CPCs include a variety of scenarios, such as:

primary and secondary cell condition change (Intra-SN CPC) within the secondary node;

a primary node initiates a primary and secondary cell condition change (MN initiated Inter-SN CPC) between secondary nodes;

secondary node initiated primary secondary cell condition change between secondary nodes (SN initiated Inter-SN CPC).

Optionally, the primary-secondary cell condition changing process between the secondary nodes initiated by the primary node includes:

step 1: a Master Node (MN) initiates CPAC, and the master node MN sends an auxiliary node adding request to at least one Target auxiliary node (Target-SN, which is called T-SN for short);

step 2: the target secondary node T-SN sends secondary node addition acknowledgement information to the MN, including one or more candidate cell configurations.

Step 3: the MN sends Early data forwarding information to the source and secondary node S-SN.

Step 4: the MN sends an RRC reconfiguration message to the UE containing the CPAC command.

Step 5: the UE sends a reconfiguration complete message and confirms that the RRC reconfiguration message is received;

step 5a: the UE triggers CPAC execution conditions and sends RRC reconfiguration completion information;

step 6: the MN sends Late data forwarding information to the source and secondary node S-SN.

Step 7: the MN sends a secondary node reconfiguration complete message to the T-SN.

Step 8: the UE randomly accesses the T-SN.

The source main node is the MN where the source main cell is located;

the source auxiliary node is the SN where the source main and auxiliary cells are located;

a Target home node (Target-MN), possibly multiple T-MNs, provides CHO candidate cells. Each T-MN may provide multiple CHO candidate cells.

A Target secondary node (Target-SN) providing SCG configuration at CHO; or provide a CPAC candidate cell at the time of CPAC. Each T-SN may provide a plurality of CPAC candidate cells.

3. And (3) condition reconfiguration:

conditional reconfiguration (CondReconfig) includes:

a condition reconfiguration identifier (condReconfigId);

execution condition (condexecu-cond);

RRC reconfiguration (condrrcrecon).

4. Measuring configuration;

the execution condition condexectioncond described above contains 1 to 2 measurement identifications (MeasId).

The specific content of MeasId is provided in the measurement configuration. One MeasId corresponds to one measurement object identification (MeasObjectId) and report configuration identification (reportConfigId). MeasObject contains cell frequency point information, physical cell identity (Physical Cell Identifier, PCI), etc. reportConfig contains measurement report related parameter configurations. For conditional candidate cells, reportConfig contains a conditional trigger configuration, such as the configuration of conditional events.

The second measurement configuration information includes at least one of measurement configuration information configured by MCG and measurement configuration information configured by SCG, i.e., the second measurement configuration information is measurement configuration information of a serving cell.

a2: a primary cell PCell or a primary secondary cell PScell in which the terminal is located;

when the serving cell in which the terminal is located is the PCell or PSCell, the above-mentioned reference configuration information is validated (validated or applied).

For example, when the first cell is a PSCell, it indicates that the condition triggering configuration is effective when the serving cell where the terminal is located is the PSCell, for example, in the SN-initiated CPC procedure, the condition triggering configuration is effective only when the serving cell where the terminal is located is the associated PSCell;

when the first cell is the PCell, it indicates that the condition triggering configuration is effective when the serving cell where the terminal is located is the PCell, for example, in the CPC or CPA process initiated by the MN, the condition triggering configuration is effective only when the serving cell where the terminal is located is the associated PCell;

And when the serving cell where the terminal is located is the PCell or the PScell, the conditional event information is effective.

That is, the physical cell identity corresponding to the first measurement object is all or partially the same as the physical cell identity corresponding to the second measurement object.

For example, the measured object MO1 in the second measurement configuration information corresponds to the frequency point F1, and the measured object MO2 in the first measurement configuration information corresponds to the frequency point F1, so that the measured result of the measured object MO2 in the first measurement configuration information is the measured result of the measured object MO1 in the second measurement configuration information.

In the embodiment of the application, global execution conditions are provided under the condition that the measurement configuration and the measurement process of the current serving cell are not changed, and candidate cells for conditional handover can be flexibly configured.

in a case where one or more measurement objects in the first measurement configuration information are not included by measurement objects in second measurement configuration information, the terminal does not measure the one or more measurement objects, wherein the second measurement configuration information includes at least one of measurement configuration information configured by MCG and measurement configuration information configured by SCG.

In this embodiment of the present application, the UE stores the reference configuration information, and after receiving the other condition reconfiguration information except the first condition reconfiguration information, the UE uses the reference configuration information to obtain measurement configuration information corresponding to the execution condition in the other condition reconfiguration information.

The method of the present application is described below in connection with specific embodiments.

In a first embodiment of the present application, the above-mentioned condition reconfiguration method includes:

step 1: the UE receives a conditional handover message, such as an RRC reconfiguration message, sent by a network side device (specifically, a first network side device). The conditional handoff message comprises at least one of:

a first item: one or more condition reconfiguration information comprising configuration information and execution conditions of the candidate cell.

The second item: and the reference configuration information comprises measurement configuration associated with the measurement identifier corresponding to the execution condition, namely at least one of the following:

at least one measurement object MeasObject, report configuration ReportConfig, conditional trigger configuration condigterconfig, conditional event condEvent (e.g. A3, A5), measurement identity measID.

In addition, the above-mentioned conditional reconfiguration information and reference configuration information may be issued to the terminal in different RRC reconfiguration messages.

The execution conditions of the above-mentioned condition reconfiguration, i.e. one or more measurement identities, correspond to measurement configuration information in the reference configuration.

Step 2: and the UE stores the reference configuration information.

Step 3: and the UE acquires measurement configuration information corresponding to the execution conditions of the condition reconfiguration information in the condition switching message by using the reference configuration, and starts the evaluation of the execution conditions.

Optionally, the UE performs the condition evaluation based on measurement results of Serving cell (Serving cell) measurement configuration information, wherein the UE maps the measurement results of the Serving cell measurement configuration information to measurement results of reference configuration information, the method comprising one or more (multiple used in parallel):

based on a Frequency point (ssb Frequency) map, for example: and the measurement result of the measurement object MO2 in the reference configuration is the measurement result of the measurement object MO1 in the Serving cell measurement configuration if the measurement object MO1 in the Serving cell measurement configuration corresponds to the frequency point F1 and the measurement object MO2 in the reference configuration corresponds to the frequency point F1.

PCI mapping is identified based on the physical cells. For example: in the Serving cell measurement configuration, a measurement object MO1 corresponds to a frequency point F1 and a PCI-List X, and the measurement object MO1 comprises a cell PCI A. The UE detects the cell PCI a. And the measurement result of the measurement object MO2 in the reference configuration corresponds to the frequency point F1 and the PCI-List Y, wherein the measurement result of the measurement object MO2 in the reference configuration comprises the cell PCI A, and the measurement result of the measurement object MO1 in the Serving cell measurement configuration.

Further, if the measurement object in the reference configuration information is not in the measurement object configured by the current serving cell (for example, a frequency point corresponding to the measurement object in the reference configuration information is not in a frequency point of the measurement object configured by the serving cell), the evaluation of the relevant execution condition is not performed;
